IMPRQVEMENT IN Bur-Tons.

The Schedule referred to in these Letters Patent and making part of the same.

To'all whom it may cc noemt: l

Be it known that I, CHARLES N.'N1oKEnsoN, of Gloucester, in the county ofEssex, and State of Massachusetts, have invented anew and useful Improvement in Buttons; and I d o hereby declare that the following is a full, true,`and`eiraotdescription of .the construction and operation. of the same, reference being had to the accompanying drawings, making apart f this specication, in which- Figures l, 2, 3, and 4 are views of a' patented button, and y l Figures 5 and 6 are views ofthe same button, with my improvement attached.

My invention is an improvement'npon the self-locking button of Frederic I. Palmer, of Springfield, Massachusetts, patented March 27, 1866. 4The patented button is so coustructed,that when it is placed upon a girment it can only be removed by destroying the button, or tearing the garment, and is unfit for further use; while my improvement provides a ready way of removing it, without injury to the button or the cloth.

A represents the stud.

B .represents the button-brm. Y

C representsa metallic spring, perforated, as shown.

When the stud A is put through the cloth into the button, the spring C engages it, and holds the parts firmly together, by catching in the notched portion of fthe stud, and it is evident that they cannot be separated, without destroying the button, when made as described in Palmers patent. A

In my improved button, I use the same spring and stud, but makethe stud with` a smaller head, and sur-l round it with a` sleeve, E, hanged, to givethe necessary hold upozn the cloth.w Aportion of the sleeve enters with the stud into the button-head, and the spring C catches in the notch of the stud A, as in the patent. To remove the stud, all that is necessaryis to press the sleeve forcibly down upon the spring, which will separate its parts, and free them from their hold ofthe stud.

For this purpose I commonly use pliers, made with a split in one of the jaws, to clear the head of the stud and bring. its force upon the sleeve, and with a depression in theA other jaw toreceive the projection on the face of the button.

Having thus described my invention,

What I claim as new, and desire to secure by Letters Patent, is i The combination of the sleeve E, stud A, and spring C, substantially as described.
